Hi,
I need to power five LED strings from one LM3404. Only one string will be ON at a time.
What do you suggest for that purpose. How mosfets can be used ?
The circuit I am using is showed below.
Vin is 12Vcc. Every string has two Luxeon LED (with Vf varying from 2,1V to 3,5V) and the driving current if 700mA.
Thank you.
